Abstract
Experiment was conducted to determine the effect of different nitrogen levels on four bread wheat varieties (Triticum aestivum L.) viz. Inqilab-91, Daman-98, Dera-98 and Punjab-96 at Gomal University, Dera Ismail Khan (NWFP), Pakistan during 2000 approximatey 2001. The experiment was laid out in split plot design having four replications using a net plot size of 2 m x 5 m. Nitrogen doses used were 0, 50, 100, 150 and 200 kg/ha. The results showed that different nitrogen levels had significant effects on plant height, total number of plants/m(2), number of grains/spike, number of spike/m(2), spike weight, biological yield, grain yield and grain protein content. Maximum plant height, total number of plants/m(2), number of spikes/m(2), spike weight, biological yield and grain protein content were observed at 200 kg N/ha. Among wheat varieties Daman-98 had maximum plant height, spike weight, grains/spike, 1000-grain weight, biological yield and grain yield. Inqilab-91 had heavier grains and the most grain protein content, while Dera-98 had the maximum plant population and spikes/m(2). Grain yield and biological yield were statistically similar at doses of 150 kg N/ha and 200 kg N/ha. However, dose of 200 kg N/ha, compared to dose of 150 Kg N/ha, significantly increased the protein content.
